Charged Particle Multiplicity Distributions in Proton Anti-proton Collisions at 540-{GeV} Center-of-mass Energy

The UA1 collaboration Arnison, G. ; Astbury, A. ; Aubert, Bernard ; et al.
Phys.Lett.B 123 (1983) 108-114, 1983.
Inspire Record 182553 DOI 10.17182/hepdata.30779

Results on charged particle production in pp̄ collision at s 1 2 = 540 GeV are presented. The data were obtained at the CERN pp̄ collider using the UA1 detector, operated without magnetic field. The central particle density is 3.3 + - 0.2 per unit o pseudo-rapidity for non-diffractive events. KNO scaling of the multiplicity distributions withresults from ISR energies is observed.

Elastic and total cross-section measurement at the CERN proton-antiproton collider

The UA1 collaboration Arnison, G. ; Astbury, A. ; Aubert, Bernard ; et al.
Phys.Lett.B 128 (1983) 336, 1983.
Inspire Record 190339 DOI 10.17182/hepdata.30668

Proton-antiproton elastic scattering at CM energy 540 GeV has been studied in the t -range 0.04 < − t < 0.45 GeV 2 . The data are well fitted by the form exp ( bt ) with b = 17.1 ± 1.0 GeV −2 for | t | = 0.04 − 0.18 GeV su 2 and b = 13.7 ± 0.2 ± 0.2 GeV −2 for | t | = 0.21−0.45 GeV 2 . A luminosity measurement combined with the optical theorem gives σ tot = 67.6 ± 5.9 ± 2.7 mb and σ e1 / σ tot = 0.209 ± 0.018 ± 0.008.

Experimental Study of Single Particle Inclusive Hadron Scattering and Associated Multiplicities

Brenner, A.E. ; Carey, David C. ; Elias, J.E. ; et al.

Inspire Record 169446 DOI 10.17182/hepdata.4112

An experiment using the Fermilab Single Arm Spectrometer (SAS) facility and an associated nonmagnetic vertex detector studied the reactions a+p→c+X, where a and c were π±, K±, p, or p¯. Extensive measurements were made at 100 and 175 GeV/c beam momenta with the outgoing hadrons detected in the SAS covering a kinematic range 0.12<x<1.0 and pT<1.25 GeV/c. Additional data covering a more restricted range in x were also gathered at 70 GeV/c incident momentum. In this high-statistics experiment, the identification of both the incoming and outgoing charged hadrons were made with a total of eight Čerenkov counters. New and extensive single-particle inclusive data for charged-particle production in low-pT hadronic fragmentation are presented. The average associated charged-particle multiplicity and pseudorapidity distributions are also given.

rivet Analysis
Comparison of $p \bar{p}$ and $p p$ Interactions at $\sqrt{s}=53$-{GeV}

Inspire Record 176647 DOI 10.17182/hepdata.30953

Results are presented from the first p p colliding beam runs at the CERN ISR, using the UA5 streamer chamber detector. p p interactions at s = 53 GeV are compared with pp data taken in the same experiment. The results are in good agreement with extrapolations of low-energy p p data.

Total p−p cross-section measurements have been made at 28 momenta, in the range (0.575÷5.35) GeV/c. The cross-section decreases monotonically with increasing momentum. No important irregularity has been found.

Measurement of the proton - anti-proton total cross-section at the S anti-p p S collider by a luminosity dependent method

The UA4/2 collaboration Augier, C. ; Bourotte, J. ; Bozzo, M. ; et al.
Phys.Lett.B 344 (1995) 451-454, 1995.
Inspire Record 380963 DOI 10.17182/hepdata.48316

The proton-antiproton total cross section was measured at the center-of-mass energy of s = 541 GeV at the S p pS at CERN using a luminosity dependent method. The result σ tot =63.0±2.1 mb is in agreement with the luminosity independent measurement performed earlier by the UA4 Collaboration.

EVIDENCE AGAINST THE NARROW S (1936) IN A MEASUREMENT OF ANTI-P P TOTAL CROSS-SECTION

Kamae, T. ; Aihara, H. ; Chiba, J. ; et al.
Phys.Rev.Lett. 44 (1980) 1439-1442, 1980.
Inspire Record 157934 DOI 10.17182/hepdata.20724

The total p¯p cross section has been measured in the S region by the transmission method with use of a beam-monitoring spectrometer. The result is inconsistent with the existence of the narrow resonance S(1936) with cross sections reported by previous experiments.
